Benefits of technology

[0007]In accordance with other aspects, the present invention relates to communication device apparatus for aggregating multiple modems in a communication device into a radio-frequency-link aggregation group to increase the data bandwidth of the radio frequency transmission from the communication device. An aggregation controller selects an aggregation algorithm and the multiple modems for the radio-frequency-link aggregation group. A connectivity service module sends subscription information and modem identifiers for the modems in the radio-frequency-link aggregation group from the communication device. An aggregation module responsive to the aggregation controller distributes data received from an application program to modems selected by the aggregation controller for data transmission from the phone whereby the data transmission rate from the communication device is increased.

Problems solved by technology

In the event of an RF link failure during transmission, the failed modem notifies the connectivity service and aggregation controller.

Embodiment Construction

[0019]FIG. 1 shows a high-level system diagram of a communication device 100 distributing data to multiple modems 104, 106, and 108 for RF (radio frequency) links to an operator network 110. Communication device 100 includes application processor 102 and multiple modems 104, 106, and 108. Although three modems are shown in FIG. 1, any number of modems might be placed in communication device 100 as represented by the variable “N” for the number of modem 108. The communication device 100 may be any one of a variety of devices that communicate wirelessly. For example, the communication device 100 may be realized as a smartphone, netbook, gaming device, PDA, tablet, or a laptop computer.

[0020]As shown, the application processor 102 distributes data packets from a single application to two or more of N modems including modems 104, 106, 108. As shown in FIG. 1 the data is distributed to modem 104, modem 106 and modem 108, and the distributed data is sent out by each modem 104, 106, 108 ov...

Abstract

Aggregating multiple modems in a communication device into a radio-frequency-link aggregation group increases the limited data bandwidth of RF data transmission between a communication device and its operator network. An aggregation controller in the communication device monitors the availability of its modems and selects modems to be used in a radio-frequency-link aggregation group. The aggregation controller also selects an aggregation algorithm. A radio-frequency-link aggregation module in the communication device distributes data to modems in the radio-frequency-link aggregation group in accordance with the aggregation algorithm. A connectivity service in the communication device notifies the operator network of the modems in the radio-frequency-link aggregation group and acknowledges that the operator network agrees to handle transmission from the radio-frequency-link aggregation group.

Description

FIELD OF THE INVENTION[0001]This invention relates to communication devices. More particularly it relates to mobile wireless communication devices.BACKGROUND OF THE INVENTION[0002]Communication devices, particularly smartphones have application processors transmitting high volumes of data to Internet servers. One limitation on data processing performed between communication devices and Internet servers is the bandwidth available for data transmission over the radio frequency (RF) link between phone and cellular tower.[0003]Not all modems support all radio technologies these days. Smartphones nowadays have multiple modems so they can select a modem that operates with the highest data transmission rate available where the phone is located. The smartphone can select which modem is used based on data transmission rate offered by an operator network and its cellular data tower. Currently, the highest data transmission rate is provided by 4G (fourth generation) networks. Many operator net...
